- Experimental Assessment of Variability in Junctionless Nanowire nMOS Transistors(2021-09-06) Michelly De Souza; BARRAUD, S.; CASSE, M.; VINET, M.; FAYNOR, O.; Marcelo Antonio PavanelloIn this work, experimental assessment of the variability of threshold voltage and drain current in junctionless nanowire n MOS transistors is presented. Die-to-die variability of threshold voltage and drain current is presented and compared to inversion mode nanowire with the same dimensions. Although the junctionless nanowires have shown larger threshold voltage matching coefficients than inversion mode devices, the variability obtained experimentally has shown to be smaller than predicted by some simulations reported in the literature. Also, it has been shown that as the channel length of junctionless nanowire transistors is reduced, the current variability becomes smaller than in inversion mode nanowires, at the same current level and dimensions.
- Analog performance of strained SOI nanowires down to 10K(2016-09-15) PAZ, B. C.; Marcelo Antonio Pavanello; CASSE, M.; BARRAUD, S.; REIMBOLD, G.; VINET, M.; FAYNOT, O.This work presents the analog performance of strained SOI nanowires for the first time. Triple gate MOSFETs made in strained and unstrained SOI material with variable fin widths from quasi-planar transistors to nanowires with aggressively scaled fin width are compared using experimental results in the temperature range of 300K down to 10K. Intrinsic voltage gain, transconductance and output conductance are the main figures of merit in this work. Transport characteristics are investigated showing that mobility behavior is the major responsible for the analog parameters dependence on temperature.
- Compact Analytical Model for Trap-Related Low Frequency Noise in Junctionless Transistors(2019-09-26) TREVISOLI, R.; Rodrigo Doria; BARRAUD, S.; Marcelo Antonio PavanelloThe aim of this work is to propose a compact analytical model for the Low Frequency Noise (LFN) in Junctionless Nanowire Transistors (JNTs). Since JNTs work differently from inversion mode transistors, the noise is also expected to behave differently. To the best of our knowledge, no analytical models have been presented for LFN in these devices. The proposed model is validated through numerical simulations. Experimental results are also used to demonstrate its applicability.
